I’m very keen to install the Laundry-to-Landscape system described in this site but do you know if it is suitable for UK plumbing or if there is one which would work in the UK? I believe you chaps work in imperial whereas we are metric over here :-S

I think it would work just fine! But you will have to do some research in finding the right parts. I installed an L2L system in France and we did find everything (in metric), but it took some time.

Make sure you keep the principals in place and don’t restrict the flow of water from the washer drain hose.

To find materials I found using a google image search the best way since the parts terminology is most likely different, and/or searching for the companies that make the parts. If there is a large irrigation store you could try to go in person and show them a diagram to find some parts, if not you’ll need to go to on-line stores.

If you find the materials please send the names/stores so it will be easier for others.
